Awards & highlights


This trial is testing the success of a new ankle implant. It will look at things like pain and function, quality of life, and how long the implant lasts.

Who is the study for?
This trial is for adults over 18 with arthritis (degenerative, rheumatoid, or post-traumatic) who need ankle replacement surgery. They must be able to consent and follow the study's procedures. Excluded are prisoners, those mentally unable to participate, non-compliant individuals, pregnant women, patients with infections or poor bone quality, and those with severe limb issues.Check my eligibility
What is being tested?
The Zimmer Trabecular Metal Total Ankle System is being tested in people needing ankle replacements due to arthritis. The study aims to track how well the implant works by looking at pain relief, improved function, life quality measures and checking x-rays for durability.See study design
What are the potential side effects?
While not explicitly listed here, potential side effects may include pain at the implant site, swelling of the affected limb(s), infection risks around the new joint and possible allergic reactions if sensitive to materials used.

Other Research
The Zimmer Trabecular Metal Total Ankle implant, like other joint replacement therapies, works by providing structural support and facilitating joint function. These implants replace damaged joint surfaces with metal and plastic components, which help to restore mobility and reduce pain. The metal components offer durability and stability, while the plastic parts mimic the cushioning effect of cartilage. This is crucial for arthritis patients as it directly addresses joint degradation, alleviates pain, and improves overall joint function, thereby enhancing the patient's quality of life.
